Microbiomul intestinal influențează somnul prin molecule bacteriene în creier.

Somnul nu va mai fi controlat exclusiv de creier, ci va interveni si microbiomul intestinal. Scrie cotidianul New York Times. Bacteriale molecules called peptidoglycans have been found in the brains of mice and appear to regulate sleep cycles, according to a study published in Frontiers in Neuroscience.

Oamenii de ştiinţă de la Universitatea de Stat Washington spun că inerţia somnului provine din comunicarea între organism şi bacteriile care îl populează, o denumire a conceptului “condiţia alobiont”. Moleculele bacteriene şi receptorii lor au fost identificaţi în diferite zone ale creierului. Acesta are variaţii semnificative în funcţie de ora din zi.

Conform articolelor publicate recent, microbiomul are o influenţă anumită asupra memoriei şi a deciziilor pe care le luăm. Pe de altă parte, studiile sugerează că somnul nu este un proces atât de simplu precum se credea, ci implică mult mai mult decât activitatea neuronală. Cercetarea arată că mesajul de a dormi mai mult leagă somnul de sănătatea intestinală.

The team at WSU will continue to investigate how these bacterial molecules communicate with the body and is exploring their potential use as therapies for sleep disorders. Studiul demonstrează-deci, că somnul apare în urma unei interacțiuni foarte complexe între creier și microbiom. Organismul uman fiind un „ecosistem” integrat.

After feeling worn down from a tick bite, the 66-year-old was admitted to Concord Hospital for about two weeks before being transferred to Massachusetts General Hospital for more intensive care, sources close to the patient told WMUR and the Concord Monitor.

Women sleep better than men – but experience the opposite - Karolinska Institutet

Women are more likely than men to report poor sleep, even though objective measurements show that their sleep is better in several respects, according to new research from Karolinska Institutet. “It’s a paradox, but we have found a possible explanation for why sleep quality is perceived so differently by men and women,” says Torbjörn Åkerstedt, professor emeritus at the Department of Clinical Neuroscience, Karolinska Institutet.
